Commands and Tips for Third-Party Devices
CTC Analytics PAL Sampler Commands
In addition to General Device Commands, the CTC PAL Samplers support the following commands and properties (please note that the display Filter level determines which commands and properties are displayed):
Status properties

Description |
Busy |
Busy/Idle |
Expert |
Indicates whether the device driver has sent all commands or whether execution of a command is complete |
CPUSerialNo |
- |
Expert |
Indicates the CPU serial number of the connected sampler |
DeviceState |
Ready/Busy/ |
Normal |
Indicates the current device status (read-only). |
StatusDescription |
- |
Normal |
Indicates the current action of the sampler. If no action is being performed, Idle is displayed |
Syringe |

Normal |
Indicates the installed syringe type (read-only). |
Inject properties

Value Range |
Filter |
Description |
AgitationOffTime |
0-99 s or Default* |
Normal |
Specifies the period during which the agitator is idle. |
AgitationOnTime |
0-99 s or Default* |
Normal |
Specifies the period during which the agitator is active. |
AgitationSpeed |
Depends on the agitator; indicated in rpm. |
Normal |
Sets the agitation speed in revolutions per minute and starts the agitator (Off deactivates the agitator). |
AirVolume |
Depends on the volume of the installed syringe; indicated in µl. |
Normal |
Specifies the air volume to be drawn for the Inject and/or WashWithSample commands (in LC_Inject and GC_Inject modes). |
FillSpeed |
Depends on the minimum and maximum speed of the installed syringe; indicated in µl/s. |
Normal |
Fill speed for the preparing fill strokes for the Inject and/or WashWithSample commands. |
FillStrokes |
0-99 or Default* |
Normal |
Number of preparing fill strokes for the Inject and/or WashWithSample commands (in all injection modes except Custom). |
FillVolume |
Depends on the syringe volume; indicated in µl. |
Normal |
Fill volume for the single piston strokes (for the Inject command in GC_Inject mode and for the WashWithSample command). |
GCCycleTime |
0 - 1440 min |
Normal |
Specifies the run time for the GC between two injections. In sample programs, this value must be set prior to the Inject command |
IncubationTime |
0 - 1440 min |
Normal |
Specifies the incubation time for the sample. |
IncubTimeOffset |
0 - 1440 min |
Normal |
Additional incubation time with respect to the previous sample in a sequence. This value can be set only once per sequence (only in HS_Progr injection mode). |
IncubTimeStart |
0 - 1440 min |
Normal |
Incubation time for the first sample in a sequence. This value can only be set once per sequence (only in HS_Progr injection mode). |
InjectMode |
LC_Inject Custom (for LC), |
Advanced |
Injection mode. In sample programs, this value must be set prior to the Inject command. |
Injector |
List of all injection objects for the installed PAL |
Normal |
Injector to be used for the Inject and/or WashWithSample commands (for all injection modes except Custom). The setting is ignored in Custom injection mode. |
InjectSpeed |
Depends on the min. and max. speed of the installed syringe; |
Normal |
Syringe speed in µl/s for injections to the sample loop/GC inlet |
PostInjectDelay |
0 - 99000 ms or Default* |
Normal |
Time between the injection and the removal of the needle from the injector (in LC_Inject, GC_Inject, HS_Single, and HS_Progr modes). |
PreInjectDelay |
0 - 99000 ms or Default* |
Normal |
Time between insertion of the needle into the injector and injection of liquid into the sample loop (GC inlet) (in LC_Inject, GC_Inject, HS_Single, and HS_Progr modes). |
PreparationTime |
0 - 1440 min |
Normal |
Preparation time. This value is set in HS_Single mode at the start time of a new sample (read-only). Corresponds to the remaining incubation time of the running sample (marked green), i.e., the time until the sample is injected. |
PullupDelay |
0 - 10000 ms or Default* |
Normal |
Indicates the delay time between drawing the liquid into the syringe and dispensing the volume that is not required (in GC_Inject mode and for the WashWithSample command). |
Tray |
List of all tray objects of the installed PAL |
Normal |
Tray to be used for Inject (for all injection modes except Custom). Note: If you select a different tray, the TrayName property is updated automatically. |
TrayName |
String |
Normal |
Indicates the name of the current tray Note: If you select a different tray, the Tray property is updated automatically. |
* Note:
For the Default parameter, the default value set by CTC on the respective device is used.
